Answer:
Take 20% of 35000 and add it
Step-by-step explanation:
20% of 35000 is 7000 so we take 35000 + 7000 which would be 42000
Answer:
P(-A) = 0.388
Step-by-step explanation:
By the <u> PROBABILITY POSTULATE: </u>
P(A) + P(not A) = 1
Here, P(A) = 0.612
So, P(not A) = P(-A) = 1 - 0.612 = 0.388
⇒P(-A) = 0.388
For the first one it's 90.5, I know cause I just took the test and it's right. The second one I'm not sure..
